It is a 5-point, self-lending alignment laser

The laser level has 5 laser dots and cross lines. That makes it a two-in-one laser level and thus you don’t need to pack two lasers when you head out to a Job site. The five-point functionality is very precise, and since the equipment can stand on its own, you can rest assured that both of your hands will be free for other tasks.

The combination makes it applicable for tasks that involve horizontal leveling, vertical leveling, plumb transfer, squaring, and layout applications. In turn, the versatility makes it great for people of various professions; including plumbers, electricians, installers, general contractors, and farmers.

Most laser levels that can perform almost as many functions as the Bosch GCL 25 usually tend to be very heavy and have a short battery life. Some are usually large and unnecessarily bulky for jobs that require mobility. The Bosch GCL 25 outdoes them in such aspects.

It measures 6.1″ x 4.6″ x 2.2″ and weighs a mere 1.1 lbs. It has an operating temperature of 14AF to about 122AF, and that should be convenient enough for most home improvement projects. Its 4 AA 1.5V batteries can last for up to 24 hours, and that is adequate time for completion of a day’s (or two day’s) work.

Physical features are better than industry standards

Ergonomically designed

As mentioned already in the introduction, this tool is a five-point self-leveling alignment, and that makes it able to perform many functions that include plumb transfer, horizontal leveling, vertical leveling and squaring.

It is a single package with the power of two traditional lasers. It also features plumb point range of up to 15 feet, a cross-line range of up to 30 feet, and horizontal points of up to 100 feet.

Furthermore, when you are using the laser, your hands are completely free to perform the actual construction tasks. Therefore, it is among the most efficient and easy-to-use in the market.

Accuracy and utility

This laser level features a smart pendulum system that self-levels to indicate out of level condition. With a cross-line accuracy of +/- 1/8″ at 30 feet and point accuracy of +/- 1/4″ at the same distance, the laser is pretty impressive in marking points and lines.

It is operated with only one button that is very easy to use and a keypad that has a line/point selection for switching between line and point functions respectively. Therefore, regarding utility, it is extremely adaptable and convenient for daily or occasional use It is practical and can be used by people who lack education knowledge in construction.

Tripod compatible

For a more accurate and steady measure, the Bosch GCL 25 is compatible with 1/4″ and 5/8″ tripod thread. It is more advanced to fit other tripods like GPL2 and GPL3 because it has a line at the top of the 5 laser dots.

Tripod compatibility is an added advantage because you can leave the laser at an exact location (height from the ground as well as distance from the wall being constructed or renovated).

Furthermore, it allows you to adjust the height and still maintain a high level of accuracy; contrary to other handheld lasers whose accuracy can be compromised by shaky hands. Fitted with a keypad for controlling self-leveling and slope models

The Bosch GCL 25 has a self-leveling ability. It also features a series of modes. The default mode gives you cross lines.

The 5-point mode gives you the five points, and it is activated using the first press of the keypad. The second press activates the horizontal line mode; the third activates the vertical line mode, and the fourth press returns you to the default mode.

Just as is the case with the equipment itself, its keypad is very easy to use, and you won’t need any specialized knowledge to understand how to use it That makes the Bosch GCL 25 great for non-professionals as much as it is for professionals.

Is a full package

Once you buy the Bosch GCL 25, you won’t have to buy many additional parts and accessories. That is because it comes as a full package with some accessories.

They include one L-Boxx 2 for storage, one BM 1 Positioning Device for point and line lasers, one laser target, one belt pouch, and 4 AA batteries. The equipment does not require installation or assembly because it comes in a ready to use form.

Therefore, once you buy the Bosch GCL 25, you won’t go through the hustle and bustle of looking for additional parts that the manufacturer failed to include.
